You can be the first;) It’s not done because no-one has done it;)
Some of my projects where I don’t think there would be too much interest I tend to lag a bit on the detailed documentation and just do it a bit more “on demand”.
Documentation contributions welcome though.
Sometimes it’s worth just dumping stuff to help close the gaps on a thread like this and then that can help build the how-to. Like I did that kind of thing over here.
